CROWN Grid aims to empower in-depth integration of resources and cooperation of researchers nationwide and worldwide. In such a distributed environment, to facilitate adoption of services, remote and hot service deployment is highly desirable. Furthermore, when the deployer and the target container are from different domains, great security challenges arise when a service is deployed to the remote container. In this paper, we present ROST, an original scheme of Remote & hOt Service deployment with Trustworthiness. By dynamically updating runtime environment configurations, ROST avoids restarting the runtime system during deployment. Moreover, we adopt trust negotiation in ROST to assure the security of service deployment. We conduct experiments in a real grid environment, and evaluate ROST comprehensively.
